Title: Managing public and private resources in a computer network
Inventor: AMAMIYA MAKOTO
IPC: G06F15/173
Filed: 2004-07-29
Abstract: A node machine 1 configuring an information network includes resources 2 located in a private zone available to private use, resources 3 located in a public zone for public service use, and a private resource security management unit 4 for management of the security of the resources 2 located in the private zone. The problem with current Peer-to-peer (P2P) systems is that it is not possible to sufficiently guarantee the security of resources especially for use in private use while discriminating the resources for public use from the resources for private use. The present invention aims at a dividing zone in which resources are located into a public and private zone, locating in the private zone the resources to which unauthorized access is rejected. It configures each community as a logical network which is guaranteed the security without consideration of a physical network.

Title: Echo sounder with pitch and roll correction
Inventor: SATOH TAKANORI
IPC: G01S15/00
Filed: 2005-04-07
Abstract: A quantitative echo sounder includes delay circuits (6), phase correction circuits (11), an incidence angle calculator (18) and a directivity correction unit (20). The delay circuits (6) adjust transmission start timing or phases of acoustic waves radiated by individual vibrating elements (3) based on pitch and roll angles measured by a motion sensing device (8) so that the direction of an acoustic axis of a transmitting beam matches a sounding direction. The phase correction circuits (11) adjust phases of received echo signals based on the pitch and roll angles so that the direction of an acoustic axis of a receiving beam matches the sounding direction. The incidence angle calculator (18) calculates echo signal incidence angle with respect to the sounding direction from phase differences among receiving beam signals obtained by four vibrating element groups (FR, FL, RL, RR). The directivity correction unit (20) corrects a measured target strength by using the echo signal incidence angle calculated by the incidence angle calculator. The echo sounder finds application in fishing.

IPC: G06N3/04
Filed: 2003-12-03
Abstract: The invention relates to a method for the real-time modelling, using neuronal networks, of the hydrodynamic characteristics of multiphase flows in the transient phase in conduits. In order to take specific account of possible flow regimes of fluids in the conduits, the inventive method consist in forming different neuronal or expert models for numerous flow regimes in the entire hydrodynamic characteristic variation range of the flows (preferably for each of same), as well as a neuronal model estimating the probability of flows belonging to each flow regime, given some of the characteristics thereof. The probabilities obtained are used to weight the estimations delivered by each of the neuronal models, hereafter referred to as experts, and the result of the weighted sum is taken as the final estimation. The invention can be used for various applications in different industries and, in particular, for the modelling of hydrocarbon flows in oil pipelines.

Title: A water motor powered by water from an uphill sewage plant
Inventor: LALLO ANTONIO
IPC: F03B17/02
Filed: 2006-06-22
Abstract: The invention entails a device which produces electric power using water that has been wasted by a sewage plant on a hill top and which is running down towards a river. Preferably, the wasted water is collected in an artificial basin, and then supplied to power generating units. Ideally, the power generating units have pistons which operate within cylinders. Water fills the cylinders and the hydrostatic head drives the pistons downwards. Valves shut off the supply of water once the piston nears the bottom. Once at the bottom, the valves associated with the piston discharge the water ballast from the cylinder. The pistons drive a crankshaft via con-rods. Several water powered units may be used in succession to produce electricity.

Title: Real time earth model for collaborative geosteering
Inventor: SUNG ROGER R
IPC: E21B49/00
Filed: 2005-01-19
Abstract: An earth model is formed in real time during drilling of a well by incorporating up-to-the-minute knowledge derived from geology, seismic, drilling, and engineering data. The process of forming the model utilizes Logging-While Drilling (LWD) or Measuring-While-Drilling (MWD) data directly from the drilling rig as the well is drilled. The LWD or MWD data is sent to visualization centers and compared with other data such as existing geological models, the proposed well plan and present interpretation of the subsurface stratigraphy. The results of the comparison enable experts to analyze anomalous results and update the geological model within minutes of penetration of a formation during drilling. Well drilling efficiency is improved, and an "on-the-spot" road map is provided for maximal reservoir contact and pinpoint accuracy.

Title: A satellite navigation and vehicle control system
Inventor: HACKETT DAVID JAMES
IPC: B60K31/00
Filed: 2007-01-23
Abstract: A satellite navigation and vehicle control system contained within a housing 10 which may be temporarily or permanently mounted within a vehicle and including a GPS signal receiving unit 11 and a further signal receiving unit 13 to receive broadcast signals representative of speed sensitive conditions such as road works, speed limit zones or speed control cameras.

Inventor: GREEN MARTIN
IPC: H01J49/34
Filed: 2007-04-30
Abstract: An ion guide or mass analyser 2 is disclosed comprising a plurality of electrodes 2a having apertures through which ions are transmitted in use. A plurality of axial pseudo-potential barriers, wells or corrugations are created along at least a portion of the length of said ion guide or mass analyzer 2 (see Figures 3A, 3B and 4). A pseudopotential barrier is also created at the entrance and/or exit of the ion guide or mass analyser 2 (see Figure 6A, 6B and 7). The amplitude or depth of the pseudo-potential or time-averaged corrugations, wells or barriers is inversely proportional to the mass-to-charge ratio of an ion. One or more transient DC voltages or DC voltage waveforms 4 are applied to the electrodes 2a of the ion guide or mass analyzer 2 in order to urge ions along the length of the ion guide or mass analyser 2. The amplitude of the transient DC voltages 4 applied to the electrodes 2a may be increased with time so that ions are caused to be emitted from the ion guide or mass analyzer 2 in reverse order of their mass to charge ratio.

IPC: G11C16/06
Filed: 2004-10-26
Abstract: A verify sense amplifier (19) reads out the data of a nonvolatile memory veil to be rewritten. The read data is compared with expected data in a comparator circuit (21). In response to a rewrite completion, a coincidence signal (MCH) is outputted from the comparator circuit (21). From a selector (23), a decode signal (STR(i)SWP(i)) of a volatile data holding unit (25) us outputted to correspond to a nonvolatile memory (MC) to be rewritten. In response to a verify instruction signal (PGV/ERV), the data read in the verify sense amplifier (19) is stored in the volatile data holding unit (25). If the control is made with the coincidence signal (MCH) in place of the verify instruction signal (PGV/ERV), the data is stored in the volatile data holding unit (25) in response to the rewrite completion. It is unnecessary to reread action information from the nonvolatile storage unit.
